Xylitol, is a compound that was identified in Germany more than a century ago and nowadays is used as a sugar substitute in numerous products. It is manufactured from plant sources such as corn-husks and birch trees. In addition to the dietary xylitol that we consume by consuming fruits, vegetables and commercial products where xylitol has been used as a sugar substitute we also produce some ourselves as part of our metabolism. While it is not well-known, it exerts several benefits that we will examine in this article. The first peer reviewed studies that brought to light some of these healthy benefits were performed in the 70s and are known as the Turku studies. Since then hundreds of research papers have been written exploring the originally found health benefits as well as other potential ones. Those benefits are attributed to its chemical structure. It belongs to the family of polyols or sugar alcohols.
The best recognized healthy benefit of Xylitol is that it guards human teeth from caries and tooth decay. A lot of research trials have confirmed this benefit and as a result, it is considered an beyond doubt fact. This is accomplished by "fighting" the microorganisms that are mainly liable for tooth decay. Research data show that it can normalize the pH of the mouth, has a bacteriostatic effect, can change the composition of the oral flora and reduce adhesion of microbes such as S Mutans on the teeth. the above, in addition to that fact that the microbes cannot utilize it as a substrate for their energy needs result in reduced risk for caries. One more interesting fact is that xylitol consumption by mothers have been proven to lower the risk of caries for their offspring, due to the fact that it reduces mother to child transmission of caries causing bacteria. Taking all of the above into consideration, it seems to be an effective prophylaxis against caries.
Xylitol is not just a tooth friendly sugar alternative. Additional healthy benefits are discovered all the time and are being researched. What are they? You may ask. Foremost, it is a better option compared to table sugar due to the fact that it has lower caloric content (40%less calories). Furthermore, it has a very low glycemic index and thus it can be used by diabetics as a sweetening agent without being afraid of a sudden blood glucose increase. Fresh research findings (from an animal study) suggest that it may even help raise bone mass and mineral content. Lastly, it has been demonstrated to be an effective prophylaxis against Acute Otitis Media in kids. All of the above, as well as the fact that it tastes almost exactly like sugar, make it a really good sweetening agent.
Almost nothing has only benefits and no weaknesses, the same goes for xylitol. Though it is a safe sugar alternative according to the Food and Drug Administration, it can cause a few gastrointestinal adverse effects. Adverse effects, including diarrhea and bloating have been reported when it is consumed in relatively big quantities. There is no universal dose that will trigger the adverse effects and habitual consumption usually results in better acquired tolerance of large quantities. Some people have reported allergic reactions as well. However, most people attribute this to consumption of xylitol extracted from corn, by individuals that are allergic to corn. Typically, the adverse effects are minor and the evidence show that it is safe.
Ultimately, a warning for pet owners and in particular dog owners: It is not safe for dogs and can cause acute health problems or even death, so make sure that xylitol products are out of reach of your dogs. If you are still not sure if xylitol is right for you and your family you might want to read some additional information about it, including articles such as candida and xylitol.
